Is the Hydraulic 2-Way Valve with Metric External Thread, SKH L/S Type compatible with standard DIN 2353 fittings and rated for high-pressure hydraulic systems?

Hydraulic 2-Way Valve with Metric External Thread, SKH L/S Type: Yes. The SKH L/S two-way ball valve is designed to DIN 2353 metric external thread standards, so it is compatible with standard DIN 2353 fittings and will integrate directly into existing installations. Constructed entirely from steel (body, ball, stem) and fitted with durable POM (ball) and NBR (stem) seals, it is built for demanding high‑pressure hydraulic systems. It operates reliably across wide temperature ranges (POM: –40°C to +100°C; NBR: –20°C to +100°C), offers smooth operation with minimal pressure loss, and provides robust tightness and wear resistance—making it suitable and safe for high‑pressure hydraulic applications.

Can the Hydraulic 2-Way Valve with Metric External Thread, SKH L/S Type be used with both POM and NBR seals for applications across its full temperature range without compromising seal performance?

Yes — but with temperature-dependent limitations. The Hydraulic 2-Way Valve with Metric External Thread, SKH L/S Type is supplied with POM seals on the ball and NBR seals on the stem and is designed to operate across the valve’s full specified temperature range only when each seal is used within its own rated limits. Specifically: - With POM seals: suitable from −40°C to +100°C. - With NBR seals: suitable from −20°C to +100°C. Therefore you should not expect full seal performance below −20°C if the valve uses NBR stem seals; for temperatures between −40°C and −20°C the POM ball seals remain acceptable but the NBR stem seals may harden and lose sealing effectiveness. For reliable operation across the entire −40°C to +100°C span, ensure any stem sealing exposed to the lowest temperatures is specified with a material rated to −40°C (i.e., replace NBR with a low-temperature alternative) or confirm a variant with compatible seal materials.
